Avalanche: Turnagain

Standard moto uptrack to 2800’. We found firm refrozen surface conditions along the flats transitioning to breakable crust on top of moist snow til about 2000’ where we found the crust got thinner and had a few inches of loose dry snow on top. The skiing was surfy feeling, and transitioned into stiff mashed potatoes around 1800’.
We dug two pits at 2400’. HS=110cm, a pair of thin crusts within the top 10cm then generally right side up and moist to the bottom. We did ID a 1cm~ layer of rounding moist facets on the ground, but no reactivity on that layer. ECTXx2.
As we walked over to peek into Main Bowl we noticed widespread surface hoar (2400-2800’) and got a couple of loud whoomphs, but didn’t see any resultant slides.
We did notice an unrelated avalanche in Main Bowl (see photos).
